CANopen Diag

The CANopen Diag is a compact, hand-held diagnostic and test device for entire CANopen networks as well as for single Devices Under Test (DUT). Being a dedicated hand-held device the CANopen Diag is especially suited for in-the-field use to perform diagnostic functions directly at machinery or vehicles. The built-in test machine engine allows the execution of time sensitive test scripts.

The selection of diagnostic functions includes physical layer and generic CAN as well as CANopen:

Physical Layer and Generic CAN

Termination resistor measurement

Voltage at pins measurements

Bus load measurements and statistics

CAN oscilloscope

Continuous logging

CANopen Network Status Overview

The status overview provides a summary of the most important information: the number of nodes found, number of boot-up messages, current bus load, longest message burst, SDO usage and LSS usage.

For each node found: its NMT status, its min/max heartbeat, its current message rate generated and node info where available (e.g. names of Virtual Devices implemented by a device)

Important Events History

The events history is a trace of the most important network events including LSS node ID assignments, NMT commands, boot-ups, emergencies, SDO aborts, first PDO use and time since reset.

Packaging

The CiA447 version of the CANopen Diag is delivered with a printed manual and packed in a rugged casing, additional cabling and a PEAK PCAN-USB Pro CAN interface. All software files are on the USB memory of the device. The provided CANopen Diag Manager software provides access to all files of the CANopen Diag (firmware versions, bootloader files, Concise DCF, CANopen Test Machine files, logs, event history, test results, screen saves). The software has access to all file versions published on our server, allowing the installation of the latest or a specific version (to re-create a previous test) of the firmware or test files.

The system offers various functions dedicated to CiA 447. The additional SDO channels and the wake-up sleep mechanism is monitored and all traces include CiA 447 symbol interpretation.

The status monitor and event history includes CiA 447 specific data and events. The monitored data includes Virtual Device information and statistics about the individual SDO clients.

The network scanner scans for CiA 447 specific information such as the Virtual Device information.

CiA 447 Tester

The CANopen Diag hand held module can be set into a CiA 447 tester mode as specified by the CiA 447 documents. Selecting this function starts a CiA 447 tester node running within CANopen Diag. It becomes an active node on the CANopen network and if no default node ID is chosen in the “CANopen Settings”, it waits for the gateway to detect it and assign a node ID to it dynamically.

Wild 13 Mode

The wild 13 mode is an extreme stress test for the gateway or another DUT. In this mode, there are multiple tester nodes. Go to the local menu by pressing the dial to activate Wild 13 mode and select 1, 3, 5, 7, 9, 11 or 13 representing the number of additional tester nodes that should run simultaneously.

To further increase the stress for the DUT, the tester in wild 13 mode will also duplicate SDO requests sent to the DUT. Where the tester in standard mode uses one SDO client to read from the DUT, in wild 13 mode the DUT will receive read requests from up to 14 nodes – one tester and 13 duplicates.
